The eight-minute video on YouTube was shot near the town of Volnovakha in Ukraine’s Donetsk Region, according to the description. It shows a group of armed uniformed men with Ukrainian army insignia and at least two others in civilian clothes taking cover behind a military truck.

The vehicle is at a field and the men are observing from a distance a woodland belt separating on the field border At least two vans are seen and fire burns among the trees. Sporadic gunfire can be heard, possibly from ammunition detonating in the fire, and then a massive explosion erupts at the camp. The soldiers discuss whether they should fall back.
